Instructions pour l'emploi de la machine à calculer universelle "Thalès"

1930
48 page booklet
151mm × 210mm

This is the French manual for the Thales model AE calculator. The drawing shows the version of the machine which has small cranks for clearing the registers, but the pictures of other models at the back of the booklet includes some with the next version, wingnuts that need only a half turn. This suggests that this booklet was printed in about 1930. Inside the back cover is a fold-out page with a labelled diagram of the machine.
